This study reports on the findings of longitudinal follow-up of visual function in a 12-year-old girl affected by congenital right hemihydranencephaly. This extremely rare unilateral brain malformation allowed the authors to gather new information on neuronal plasticity and functional compensations of the visual system across a period of 10 years. An extension of the preserved right visual hemifields above the middle line and strategical eye or head positions developed to increase visual functions are discussed. In addition, ophthalmological and orthoptical findings, as well as the development of monocular grating and linear acuity, are described.
本研究报告了一名患有先天性右侧半侧积水性无脑畸形的12岁女孩视觉功能的纵向随访结果。这种极其罕见的单侧脑畸形使作者能够在10年的时间里收集有关视觉系统神经元可塑性和功能代偿的新信息。文中讨论了中线以上保留的右侧视觉半视野的扩展以及为提高视觉功能而形成的策略性眼位或头位。此外，还描述了眼科和视光学检查结果，以及单眼光栅和线性视力的发展情况。
